1. Taylor series are special power series that are defined from a function f(z) atz = a by fitting higher and higher degree polynomials T, a(x) to the curve at the point (a, f(a)), with the goal of getting a better and better fit as we not only let the degree grow larger, but take a series whose partial sums are these so-called Taylor polynomials Tm,a(x) We will explore how this is done by determine the Taylor series of f(z)...
A function f, which has derivatives for all orders for all real numbers, has a 3rd degree Taylor polynomial for f centered at x = 5. The 4th derivative of f satisfies the inequality f^(4)(x) ≤ 6 for all x the interval from 4.5 to 5 inclusive. Find the LaGrange error bound if the 3rd degree Taylor polynomial is used to estimate f(4.5). You must show your work but do not need to evaluate the remainder expression.

5. A function f has Taylor series (at 0) f(x)=0+2x+ 4x2/2! + 3x3/3!+... Assume f−1 exists. Find as much of the Taylor series of f−1 (at 0) as you can. (Since you only know the first few terms of the Taylor series for f, you can only figure out f−1. (Hint: There are two ways of doing this problem. One is get the derivatives of f−1 from knowing the derivatives of f; we talked about the first derivative in January...
1. (a) We want to develop a method for calculating the function sint dt f)-inf t 0 for small or moderately small values of x. This is a special function called the "sine integral", and it is related to another special function called the "exponential integral". It arises in diffraction problems. Derive a Taylor-series expression for f(x), and give an upper bound for the error when the series is terminated after the n-th order term. [HINT: (-1)"*z ? + R...
